First, I want to thank Christinmk for the drawing. I remember the discussion back a few years ago, but never got around to checking the flowers out on mine. I had bought 3 Adenophora plants years ago. They do have beautiful flowers, but they just took over my gardens, and I mean really bad. I've tried Roundup several times, but I can never get all of them. I can't dig them out because of the other plants, and besides, you leave any roots in, they'll come back full force. So I keep trying Roundup and it does help. I use a small brush sometimes because of other plants. It doesn't matter if you clip off the flowers, they still spread by roots. Ok, I've just checked the flower on mine. It has the bulb at the end of the style, so it's Adenophora. I just read the link for Adenophora vs the evil twin, and I definitely have Adrenophora. In the article, they say Adenophora doesn't spread like this, but it does. Also, my flowers are not all on 1 side like the link for c. Rapunculoides shows. As for c. rotundifolia, harebell, I've had that for 15 or so years. I love it. Blooms from mid June thru, quite often, until early November. Spreads a little, but not a problem at all. Kat

It's a type of Rumex, or dock. A very common weed and one with a deep taproot that must be removed completely to prevent the plant from regenerating. And it does seed freely so avoid letting the plant flower. It will respond to any broadleaf weed killer but that must be used carefully if the weed is intermixed with desirable plants.

I am jealous of your loaded blue mouse ears. Mine are blooming but not so profusely. I see your praying hands is shoot up its brachs. I noticed four on mine today after several years of not blooming. Beautiful plants in you yard!

Actually loads of plants would "survive" tractor traffic. You shave off the top part of the plant, and most self-respecting weeds have root systems that will happily and quickly sprout. So occasional heavy traffic is probably not a problem. As to weeds being very good at being weeds, the issue is whether you have those weeds. If not, you need to introduce them.
